FXdreema is a no-code, drag-and-drop tool designed for building Expert Advisors (EAs) on MetaTrader 4 (MT4) and MetaTrader 5 (MT5). One of the key features of FXdreema is the use of constants (inputs) and variables, which allow traders to define custom values that can be used across multiple blocks in an EA.

📌 What Are Constants (Inputs) & Variables?

In FXdreema, Constants and Variables serve as placeholders for values that are used throughout an EA strategy. These values can be adjusted, stored, or referenced by different trading blocks.

📍 Constants (Inputs):

• Constants are predefined values that remain fixed unless modified manually.
• They can store values such as lot size, risk percentage, stop-loss distance, or time settings.
• Constants can be used across multiple blocks in the same EA.
• They help maintain consistency in trading rules and make backtesting easier.

📍 Variables:

• Unlike constants, variables can change dynamically during the execution of an EA.
• They are used to store and process data like price levels, indicator values, or open order counts.
• Useful for trailing stops, grid trading, and conditions that evolve over time.

🛠 How to Use Constants and Variables in FXdreema?

1️⃣ Creating Constants in FXdreema

1. Go to the Constants (Inputs) section.
2. Click on “+ Add New” to create a new constant.
3. Define the type (int, double, string, char, bool, datetime, color, ENUM_TIME, etc.).
4. Assign a name, value, and description (e.g., “Risk_Percentage,” 2.0, “Set risk as 2%”).
5. Click Update to save the changes.

2️⃣ Using Constants in EA Development

• When setting parameters for buy/sell orders, indicators, or risk management, select the constant instead of manually typing values.
• If a constant value is changed, all blocks using it will automatically update—making modifications simple and quick.

3️⃣ Working with Variables

• Variables are updated dynamically during EA execution.
• Example: A variable can store the highest high of the last 20 candles and adjust trailing stop levels accordingly.

🔥 Benefits of Using Constants & Variables in FXdreema

✅ Easier EA Optimization—Modify a single constant to adjust all blocks at once.
✅ Better Risk Management—Predefine stop-loss and take-profit levels using constants.
✅ Flexible Trading Strategies—Use dynamic variables for grid trading, martingale, and trend-following strategies.
✅ Quick Adjustments for Backtesting—Change constant values to see how different settings impact historical performance.
